Table S2: Final residues of four herbicides in rice hull sample. The degradation dynamics of the four herbicides in paddy fields appeared to follow the first-order kinetic reaction and were calculated according to the following equation: Ct=C0ekt, where Ct and C0 are the concentrations of herbicides at time t and time 0 after spraying (mg/kg), respectively, and k is the degradation rate constant [37,38]. The national estimated daily intake (NEDI) of the four herbicides was defined by the following equation: NEDI=STMRFi/bw, where the average body weight (bw) of an adult in China was estimated at 60 kg, and the intake of an adult per day (Fi) was 0.3 kg per Chinese person when consuming rice, which was provided based on the dietary guidelines issued by the Health Ministry of China [55].
